DRINKING WATER CASE STUDIES AND WHITE PAPERS

• EPA Researchers Develop Tool To Assess Onsite Non-Potable Water Reuse For Buildings Across The U.S.

  Increasing pressure on water resources has led to greater water scarcity and a growing demand for enough clean water. Many communities across the country have initiated, or are in the process of developing, centralized systems for planned water reuse. Water reuse is the concept of intentionally recycling, treating, and reusing alternative water sources. Federal government agencies and the water user community are coordinating their efforts to advance the adoption of water reuse and ensure the security, sustainability, and resilience of water resources. The National Water Reuse Action Plan (WRAP) describes these collaborative actions.

• What Is A Purple Pipe?

  For the city of Beaverton, Oregon, the “Beaverton Purple Pipe” is a new water system that routes treated stormwater to irrigate green spaces like parks, school grounds and residential yards.

• AMERICAN Pipe And Valves Ensure Georgia Project Flows With Ease

  The estimated $30-million West Side Loop 48-inch Replacement Project is one of three capital projects being conducted by the Cobb County-Marietta Water Authority to provide additional water to western Cobb County and Paulding County in Georgia. For the project, a 48-year-old, 36-inch pre-stressed concrete cylinder pipe (PCCP) that recently failed is being replaced with 48-inch ductile iron pipe.

• Drinking Water Treatment - Coquitlam Water Treatment Plant, British Columbia

  In 2005, in response to changes to the Canadian Drinking Water Quality guidelines, the Greater Vancouver Water District Board approved a proposal to upgrade the Coquitlam WTP with UV treatment technology to act as the primary means of inactivation.

• Leveraging AMI To Identify & Repair Leaks In North Miami Beach

  Until recently, the City of North Miami Beach relied on traditional walk-up, manual meter reading, and a leak detection service that visited quarterly to survey areas of its distribution system. Surveyors would visit two weeks per quarter, helping city staff systematically go from one end of the 550-mile pipeline system to the other in one-mile sections—it took one and a half years to get through the city’s 25-square-mile service territory. While the city was able to maintain its system and identify leaks, the process was labor intensive and the city understood that automating meter reading and leak detection could be done simultaneously, saving precious time, staff resources, money—and most importantly, water.

• Minimizing Water Outages With Targeted Valve Control

  The Town of Holly Springs, NC, used Hydra-Stop's Insta-Valve 250 insertion valves to repair a leak in a transmission line without causing water service outages to over 40 residences. This solution saved the town from widespread outages and other costs associated with a system shutdown, providing better control, cost reduction, and long-term value.

• Santa Barbara, Curaçao Desalination Plant: Six Years Of Operation Of LG Chem Thin Film Nanocomposite (TFN) SWRO Membrane

  The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.

• Profile II Analytical Results, Mine Site Processing

  Increasing profitability through efficient tailing and pregnant solution processing. 

• Optimizing Leak Detection Using Virtual District Metering Areas (vDMAs)

  Today, progressive utilities are using digital technologies to create virtual district metering areas (vDMAs), eliminating the limitations of the physical DMA by utilizing data to provide actionable insights into the condition of their networks.

• City Of Punta Gorda Improves Distribution System Residuals By Installing The Tank Shark® Mixing System In Two Million Gallon Punta Gorda Isles Reservoir

  Historic Punta Gorda, located on the shores of scenic Charlotte Harbor on the west coast of Florida prides itself in the proactive management of its water supply. With the responsibility of providing water to over 34,000 customers in the 38 square mile service area, Punta Gorda manages 237 miles of distribution pipe and two water storage facilities. The 1 million gallon (MG) Burnt Store elevated tank and the 2 MG Punta Gorda Isles ground storage tank provide distribution system balance as well as the ability to meet peak demands and fire protection capacity.
